Seal pups listen for long distance calls to locate their mothers

Antarctic fur seal pups identify their mothers by detecting the mother's vocal pitch at longer distances and using other components of the vocal signature at closer range. The study found that frequency modulations propagate reliably up to 64 meters, while amplitude modulations are degraded for distances over 8 meters.

Solar cell research funded by US Department of Energy

Penn State researchers are developing new, ultra-high efficiency photovoltaic cells using a novel tracking system to concentrate sunlight 400 times over. The goal is to create standard rooftop solar panels with competitive manufacturing costs and double the efficiency of existing solar panels in sunny regions.

One dose or 2? Cholera vaccination strategies

A new modeling study suggests that a single dose of cholera vaccine could be as effective as the traditional two-dose regimen in preventing deaths. The researchers estimate that a one-dose campaign reaching half the population would have averted over 78,000 cases and prevented 738 deaths.

Genetic analysis supports elevating Cape Parrot to new species

A recent study published in PLOS ONE suggests that the Cape Parrot should be classified as a distinct species due to its genetically distinct markers. The research analyzed DNA samples from five Poicephalus species and found that the Cape Parrot shares common ancestry with other subspecies only at around 2 million years ago.

NSF funds industry/university center for atomically thin coatings

The NSF-funded Industry/University Collaborative Research Center will design and develop advanced two-dimensional coatings to address fundamental scientific and technological challenges. The Center for Atomically Thin Multifunctional Coatings (ATOMIC) aims to create spin-out companies and solve issues like corrosion, oxidation, and abr...

Falling off the wagon with Facebook

Research presented at the American Psychological Association's convention found that participants who attended more face-to-face meetings had greater success in achieving and maintaining sobriety. Online support groups on Facebook did not show similar results, with participants reporting a higher likelihood of dishonesty online.

People walk slower, swerve when texting while distracted

A study found that adults who text while being cognitively distracted exhibit a more cautious gait, including increased obstacle clearance and decreased ability to walk in a straight line. The researchers suggest this adaptation may help prevent accidents when faced with cognitive challenges.

Scientists gain new insights into 'antenna' of human cells

Researchers have identified a group of genes implicated in common inherited diseases, known as ciliopathies, which can be diagnosed more quickly and could lead to new treatments for patients. The study, published in Nature Cell Biology, found that defects in cilia, microscopic 'antennae' on cells, are responsible for the disorders.

Conflicts 4,000 years ago

A new LOEWE research focus at the Goethe University Frankfurt is investigating Bronze Age forts between the Taunus and Carpathian mountains. The study aims to uncover the social historical perspective of violent conflict during this period, comparing it to early Middle Ages conditions.
